Only if you treat downvotes as bad. My own comments on this thread have received a fair number of both upvotes and downvotes. I consider when that happens (assuming I haven't been overly antagonistic, which I don't think I have been) that I've hit a raw nerve. I could be wrong, but alternatively I could've said something someone isn't willing to hear. That can be useful feedback in its own right (though I prefer the clarity of comments over votes).
Maybe it's me, but it's rare that my comments get more that 10 votes (up/down) - and as such, I don't make anything of votes to my comments; statistical significance, poor sample, puppet accounts, etc.
What I do make something of is meaningful responses to my comments.
Sure, such feedback is rare, it does require significant feedback in both directions, it doesn't work with single upvote/downvote swings.
It's also very obvious when you've said something that annoys one individual as you can get a string of downvotes in quick succession across multiple comments. Such feedback is easy to spot and see as childish, so I enjoy it for what it is instead.
That said, I much prefer comments, even those that disagree with me.
I'm aware I can say things that people don't like, yes, but in some cases it's more beneficial to have a respectful debate than to stay silent. If I'm not prepared to listen to opposing opinions then I'll be robbing myself of getting a deeper understanding.
A downvote is second best to a comment explaining the reason behind the disagreement. A comment is better feedback than a vote because you can get a clearer understanding from a comment.
Hm, is it an echo chamber if the dissent to the majority is also present and up voted? I feel like you didn't read the second half of my comment or I don't understand what you mean.
